AiRrsearch t3 turbo on a 3100

[gmmalibu]

Can anyone tell me how to to a remote mount setup instead of under the hood, im looking to mount my turbo where the muffler goes. wut materials would i need? and will my 3100 handle my t3 turbo? please help. thanx

Recently had an '04 350Z in the shop with a rear mount setup. Looked pretty cool, loud as hell. It takes a little extra pipe and a mile of heat wrap but he had pretty good results.

[gmmalibu]

would you happen to know how much boost a stock 3100 can handle?

[86FieroSEv6]

All things being equal, that means rings and bearings in good shape as well as the oil pump and cooling system . . . I would hazard to say that 6psi should be plenty and within the tuning abilities of the stock system. You must have a fresh fuel pump (an upgrade here isn't much more than the OE pump) and adjustable fuel pressure regulator.

[gmmalibu]

its not completly stock its has a aftermarket intake, 2 1/4" piping from the cat back, 8.8 milimeter plug wires, the engine is a 3100 but has a fuel pressure regulator of a 3400, and a hyper ground kit, and a k&n oil filter, would that make a difference in how much boost it can handle, or is it irrelevant n will only hold 6psi, because i want to run at least 8 psi max 10psi without really doing a major overhaul to push 12psi

[86FieroSEv6]

It's just that I don't have any personal data on what happens above 6psi to the stock head gaskets and TTY bolts. I would venture to say that if you upgraded your head gaskets and used ARP studs you could probably squeeze it up a bit. Beyond 10psi you are probably wanting some better connecting rods.

What would i need to control boost besides a blow off valve and an external wastegate, im looking to just boost up to 8psi

What are the specs on the turbo?

[gmmalibu]

AiResearch t3 turbo 48 trim thats as much as i can find out about it, i think the turbo came from a mercedes 300d but not sure, whoever had it before cancelled the internal wastegate so i have to use an external one

You're asking questions that suggest there is a lot more reading to do. Rear mount turbocharging should be a last resort to no other option choice. The cars that have them usually have very little space to spare under the hood.

A T3 turbo has several options available to help get around what I'm guessing is an internal wastegate welded shut, the T3 is very common and replacement turbine housings close to growing on trees. You should post a picture of what you have.

Head gaskets are the least of your worries at the boost level you're considering unless you run into detonation and even at that point you are more likely to damage a piston than a head gasket.

The efficiency dynamics governing rear mount turbos is very different than a long distance intercooler such as a front mount in a Fiero where the cooling effect on the air charge is beneficial over the travel route but detrimental when applied to the exhaust in a rear mount turbo, that's why the Z owner has his exhaust system heat wrapped that far away from the exhaust manifolds.

One thing you'll notice on a turbo car with an audible turbine spool is that the hotter the exhaust is at idle the faster the turbine spins at idle and the more audible it becomes at idle revealing the significance of the heat which keeps the volume of the exhaust gases expanded speeding up the exit. Cooling the exhaust such as over a stretch the length of the car does just the opposite and you can't fully make up for that by using a smaller turbo and it certainly will not equal the performance of the same car with the turbo hanging off the exhaust manifold. Those are things to consider, the cool factor vs. the performance factor. It works but I believe you would be much happier with a front mount turbo especially if you have little experience with the process.

Wish I had had someone to reason away building the twin turbo setup I built. It made switching to a single all the more clearer as the better choice from the start. Put it on paper first and plan it out to the end, that will save you lots of money and time.

will the tranmission be able to handle the boost coming from the engine

[payback]

youll be OK with a .48, but as joseph upson pointed out a remote system is far from optimal. Get a battery relocation kit.

Should be fine with lower boost levels. Get a tranny fluid cooler, theres no reason not to the things are $40 bux. Do some research to get info, also to get your own opinions.

[timg]

For boost levels of 5-7 psi, your engine and transmission should be fine. Once you go over 7 psi, careful tuning will be required.

Your transmission life will be shortened once you go boosted. If it's marginal now, it won't last long under boost. If it's working great, you may get another 30-60k miles out of it.

With turbo specs that generic, we can't really tell you how it would work. That's the big problem with junkyard/used turbos. Designing a system around used parts is much more difficult than designing it around new, well documented parts. It will probably take a lot of trial and error to get it right and by the time you're done you will likely either have spent more money than if you did it right to start with (using new, properly spec'd parts) or with inferior power and/or reliability.

Joseph is right. Rear mount turbos are turbo setups of last resort. They will never spool as quickly or make as much power as a decent under-hood setup. They typically are a bit easier to build, but require more piping, weight, and oiling components. You should really consider an under-hood turbo setup.

here is the basic idea... rear mount is the easy way to turbo but it will not make tons a power/fast track times.. It works but not as well as a underhood turbo setup. that small of a turbo should be fine as a rear mount turbo, but probably a bit small on the underhood setup.
- Remove muffler
- install turbo in place of muffler (custom piping/flanges required)
- External gate before the inlet of the turbo and dumping out (or out the back)
- run LONG ASS oil line to turbo
- Oil return pump to get the oil back to the engine (dumps back into oil fill cap)
- Boost pipe from outlet of turbo to the intake
- FMU on the fuel return line (unless using fuel management/tune)

will the transmission hold up to 8 psi or do i have to modify it as well
